An improved fan for producing cooling or heating effects, which is essentially characterized by being mounted inside a preferably metallic cylindrical casing, on the front of which and in front of the fan there are located a series of electrical resistances, arranged in the slots of a circular plate of refractory material, through which the fan passes an air current, in such a way that by connecting the resistances a heating effect will be obtained and by disconnecting them, cooling will be obtained.
